Question

1, The following are statements regarding structural features of the single subunit peptide in the diagram provided. Which statement is correct?

options:

Interaction "c" represents quaternary structure.

Interaction "e" is more likely to be sensitive to changes in pH than interaction "d".

Interaction "b" is the result of the reduction of two methionine amino acid residues.

The R groups in the region labeled "a" point to the interior of the alpha helix.

Interactions b, c, d and e are all noncovalent.

Interaction "e" is a hydrophilic interaction.

Interaction "b" is least susceptible to denaturation.

Interaction "d" is strongest when located near the surface of a protein where it can interact with water.

Explanation / Answer

Ans Correct statements are

Interaction "e" is hydrophobic interaction

interaction d is strongest when located near the surface of a protein where it can interact with water. This is due to the interaction d is ionic interaction of NH3+ and COO-.
